The IDT71321SA20TF is a high-speed 2K x 8 dual-port static RAM designed for asynchronous memory applications. It features a maximum access time of 20 ns for commercial applications and 25 ns for industrial applications. The device operates on a single 5V power supply and has a typical active power consumption of 325 mW, with a low standby power consumption of 5 mW for standard versions and 1 mW for low-power versions. This memory chip includes internal interrupt logic for interprocessor communications and supports independent, asynchronous access to any memory location from both ports. It is available in multiple package options, including 52-pin PLCC and 64-pin TQFP, and is suitable for industrial temperature ranges from -40°C to +85°C. The device also supports battery backup operation with 2V data retention for low-power versions. Engineers seeking a dual-port SRAM solution with low power consumption and high-speed access for their applications may find the IDT71321SA20TF a suitable choice.
